Product Description

The CP Pistons SC7411 is a set of four forged 2618 aluminum pistons engineered for the Subaru FA24DIT 2.4L turbocharged boxer engine, with confirmed fitment in the 2022-2025 Subaru WRX (VB) and compatibility across all FA24DIT applications including the 2019-2025 Ascent, 2020-2025 Legacy XT, and 2020-2025 Outback XT/Wilderness. At 94.10mm bore and 10.6:1 compression ratio with a -11.54cc dish, this set is built for forced induction, high-boost builds where the superior tensile strength and thermal stability of 2618 aluminum is essential. Stock 86mm stroke and 129.3mm rod length are retained, requiring no crank or rod modification. CP-Carrillo designs all pistons through extensive R&D at their Irvine, California facility, with full manufacturing performed in-house from raw forging to final CNC machining. The SC7411 is compatible with oversized valves and high-lift camshafts, making it suitable for comprehensive engine builds alongside cylinder head modifications. Optional upgrades including gas ports, skirt coating, ceramic top coat, and heavy-duty wrist pins are available through CP-Carrillo directly for builds targeting extreme power levels. Important: the FA24DIT turbocharged engine shares the same 94mm bore as the naturally aspirated FA24D used in the Subaru BRZ and Toyota GR86 -- these pistons are for the turbocharged FA24DIT only and are not intended for naturally aspirated applications. This product is not CARB legal and is not for sale or use in California.
